Research | Current

Recent research has focused on bioorganometallics with a particular interest in the synthesis of anticancer active mono-, di- and trinuclear compounds with (thio)pyr(id)onato ligands. We design our complexes to exhibit their antitumor activity in the tumor tissue (focusing on selective transport into the tumor) or to possess new modes of action (e.g., dinuclear Ru complexes with lower toxicity than Pt compounds and non-common DNA binding modes). We were the first who could demonstrate that the linkage of two Ru centers can result in improved anticancer activity, possibly by crosslinking biological macromolecules. The most active complex was up to 10-fold more active in resistant cancer cell lines than in the respective wild-type cells. These results indicate that the compounds might be an option to tackle the common problem of developed resistance of tumors, frequently occurring during chemotherapy. Furthermore, we have modified Ru(arene) complexes with maleimide to react selectively with thiol-containing biomolecules, introduced a multitude of bioactive ligand systems and created orally available metallodrugs.

In our group the development of new drug molecules is complemented by extensive bioanalytical studies to elucidate the mode of action of tumor-inhibiting metal complexes. Biophysical methods (separation methods, online and offline MS) have been developed and applied for studies e.g. on the Ru(III) bisindazole compound KP1019. Those experiments contributed to the selection of KP1019 for clinical development, being currently in clinical phase I/IIa trials in a modified formulation. Capillary electrophoresis hyphenated to inductively-coupled plasma mass spectrometry (CE-ICP-MS) was used to show that a Ga-based drug candidate binds in human blood serum preferentially to transferrin, whereas Ru complexes are most often found mainly attached to human serum albumin (HSA). Application of modern mass spectrometry methods resulted for the first time in the binding site elucidation of a metal-based drug on proteins by employing top-down mass spectrometric approaches. The bioanalytical studies are rounded off by the introduction of new methods, such as the first coupling of microemulsion electrokinetic chromatography (MEEKC) to ICP-MS and the development of a new interface to couple CE with ICP-MS. More recently, we have reported studies on the identification of proteins as binding partners for metal-based anticancer agents in cancer cells and we have developed interest in the structural characterisation of the adducts formed between proteins and metal species, all of which help us to better understand how the compounds behave in a biological environment and how to improve their pharmacological activity.
